2. **Check Authentication Settings**: Make sure your authentication settings are properly configured on both Telnyx and Vapi sides. Incorrect authentication can prevent proper audio transmission.
3. **Transcriber Settings**: Try changing the transcriber. Some users have reported that switching from Deepgram to another transcriber like Azure resolved similar issues where the bot couldn't hear them.
### Audio Input Troubleshooting
1. **Enable Recording**: Ensure that recording is enabled by setting recordingEnabled
to true for your calls.
2. **HIPAA Compliance Setting**: Check that the hipaaEnabled
setting is turned off, as recordings won't be stored if hipaaEnabled
is set to True, even if recordingEnabled
is set to true.
3. **Voice Activity Detection (VAD)**: The VAD settings might need adjustment to properly capture your speech when it starts.
4. **Telnyx Denoiser**: Telnyx has a built-in denoiser feature that can be enabled to potentially solve audio issues. Check if this is enabled in your Telnyx settings.
### Network and Connectivity
1. **Network Configuration**: Verify that your network allows traffic on the SIP protocol and that any firewalls or NATs are configured to allow SIP messages to pass through.Vapi Support Bot
